Hi all,
Can anyone help me? Or guide me to solve this error.
I get an error like this when I run my crystal report.
Your help is appreciated.

"A string required here.
Error in File C:\DOCUME~1\COUNTER\LOCALS~1\TEMP\temp_ebfc56a7-f48a-46b4-9335-709e5682573c{E5F4DBBE-6BE3-4C08-A7A8-63F7769CC81C}.rpt:
Error in formula <GroupID>,
'stringvar ID := {Consignment_Sales_Report.GroupID};
'
A string required here."

Below is my code.

stringvar ID := {Consignment_Sales_Report.GroupID};
mid( ID , 1,len ( ID));
cstr(ID)

do you need to save the crystal Report
